Built around the long-roof Commodore, the MPI Automotive SSMKHN0269 is a 2.5in dual extractor-and-exhaust package listed to fit the VT-VZ V8 in wagon body. The wagon's extended floorpan and rear overhang change how a dual system has to route, and this kit is specified for that shape rather than the sedan or ute.

Why a wagon-specific package?

A VT-VZ wagon carries a longer rear section and a different tailgate area than the sedan it shares a front end with, so the dual pipework, hangers and rear muffler placement all have to suit the estate floorpan. The SSMKHN0269 is listed against the wagon for exactly that reason — it's the same V8 up front, but the routing behind the diff is its own problem to solve.

What's in the system?

This is a full extractor-back package, not just a header set: tube-and-merge extractors replace the restrictive cast manifolds at the heads, then the system runs as a 2.5in dual the length of the car and finishes through a rear muffler each side. Replacing the cast manifolds is where most of the breathing gain on these V8s comes from, and the matched 2.5in dual keeps the flow consistent rather than necking down to a factory bottleneck.

What does the 2.5in dual suit?

A 2.5in dual is the street-oriented sizing for these Holden V8s — paired pipes keep gas speed up for low-down and mid-range response while still flowing more than the standard single-bank plumbing. With a muffler each side rather than a hotdog, the SSMKHN0269 is pitched at a fuller note without crossing into raucous, which suits a wagon that still does family-car duty.

How is fitment confirmed at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits MPI extractor systems in-house across the Illawarra. The SSMKHN0269 is listed to fit the VT-VZ V8 wagon; because it's a major-spend item we check your exact series, manifold type and rear hanger arrangement before ordering so the system that arrives is the one your car actually takes. Send your build and we'll book the bay.

Common questions

Is the SSMKHN0269 just the extractors or the whole system?
It's a complete extractor-back package — extractors at the heads plus the 2.5in dual exhaust and rear mufflers, not headers on their own.
Will it fit my VT-VZ Commodore wagon?
It's listed to fit the VT-VZ V8 in wagon body. The wagon routing differs from the sedan, so confirm your exact series with the workshop before ordering.
